It's interesting how people who are passionate about a hobby will find ways to overcome their disabilities. The OP for a recent topic has glaucoma, someone else chimed in with a different eye issue (macular degeneration), and in another forum section was an individual who is bedridden. While these are severe obstacles, we find ways to adapt and compensate.

In my case, the disability is Parkinson's. This causes tremors in my right arm and leg. Unfortunately, cameras are designed to be held and manipulated with the right hand...

Photomacrography is perfect for me... The camera is firmly fixed, not handheld. I use a remote shutter release (which my right hand can usually do). Fine focussing for stacking is done with my left hand. There's no hurry to set up to capture the fleeting moment, and I'm ok with that.

Improvise, Adapt, and Overcome. And have fun._________________Never stop learning!
